Australian Indigenous HealthBulletin 18(3) Introduction About this review Cancer is a major cause of illness in Australia and has substantial The purpose of this review is to provide a comprehensive synthesis social and economic impacts on individuals, families and the of key information on cancer among Aboriginal and Torres Strait community [1]. Findings from the Australian Burden of Disease Islander people in Australia to: (1) inform those involved or interested Study showed that cancer was the greatest cause of health burden in Aboriginal and Torres Strait Islander health; and (2) provide in Australia. Socially disadvantaged groups and Indigenous people the evidence for those involved in policy, strategy and program are particularly at risk, Aboriginal and Torres Strait Islander people development and delivery. The review provides general information experience nearly twice the cancer burden of non-Indigenous on factors that contribute to cancer among Aboriginal and Torres people. The most common cancers diagnosed among Aboriginal Strait Islander people. It provides detailed information on the extent and Torres Strait Islander people are lung, breast (females), bowel of cancer among Aboriginal and Torres Strait Islander people, and prostate (males) [2]. including: incidence, prevalence and survival data; mortality and burden of disease and health service utilisation. This review discusses Cancer is the term used for a variety of diseases that cause damage the issues of prevention and management of cancer, and provides to the DNA (genetic blueprint) of the cells resulting in uncontrolled information on relevant programs, services, policies and strategies growth (cells normally grow and multiply in a controlled manner) that address cancer among Aboriginal and Torres Strait Islander [3]. If cells spread into surrounding areas or to different parts of the people. It concludes by discussing possible future directions for body (metastasise), this invasion is known as malignancy. A benign combatting cancer in Australia. growth is a mass of cells that doesn’t spread to surrounding areas or metastasise. Malignant (cancerous) or benign (non-cancerous) This review draws mostly on journal publications, government abnormal tissue growths may both be referred to as neoplasms. reports, national data collections and national surveys, the Cancerous cells can arise from almost any cell, so cancer can occur majority of which can be accessed through the HealthInfoNet’s almost anywhere in the body [4]. Different types of cancer are Australian Indigenous library (https://healthinfonet.ecu.edu.au/ distinguished by the location in the body where the disease began key-resources/publications). (for example, lung) or by the cell type involved (for example, basal When referring to Australia’s Indigenous people, the HealthInfoNet cell carcinoma). prefers to use the terms Aboriginal, Torres Strait Islander, or Aboriginal and Torres Strait Islander. However, when referencing information from other sources, authors may use the terms from the original source unless they can obtain clarification from the report authors/copyright holders. As a result, readers may see these terms used interchangeably with the term ‘Indigenous’ in some instances.
